`invented a certainv new and useful Improvement lnvMachines'tfo'r Making Looped Fabric`,f

. of ,which the following is a full, clear, and exact description, reference .being had to'the accompanying drawings, form/ing part of this l vfor knitting fabric-'and simultaneously form.

specification. v j My present invention relates "to machines ing thereona series of loops vwhich are knit-A 1 tedinto the fabric and form a part thereof.

My machine is particularly intended for Amaking harness Vpads`,such as are shown and described in my cotemporaneous application, -Serial No. OI,432, iiled February 24, 1894.

V My present .invention consists in yfeatures of novelty hereinafter f'ullydescribed and poin-tedout inthe claims.

.Figure I is al planview, illustrative of my improved machine, the dial shaft being shown in section. Fig. II is a detail, side elevation. Fig. III is a detail, Vertical sect/ion. FiglV is a detail, vertical section, showing the loop points withdrawn froml Working posi/tion.` F1g.v is a detail, perspectivel view. Fig. VI

. is a detail, vertical section with theI loop points in their outer or Working position. Figs. VII and -VIII are detail, Ytop views. Fig. IX is a diagram. v

' Referring to the draWing's,-1.repres'ents the needles of an ordinary machine,their arrangement-and mode of operation beingwell nnderstood, and require no explanation here.

2 represents a dial plate carried o n a shaft or rod 3, 'and adapted to rest within-thencevdle cylinder, or to be removedftherefrom, as

l shown in my patent, No.` 407,960, issued'July In my improved machine, th dial 2' has a number'ofAiiXed points 14, projecting from its' periphery, each point having preferably a recess 5 in its outer end. l g

`In the operation of the machine, the dial turns with the needle cylinder, its movement being caused ,by ears thereon, which engage with projections-on the inner face of the nee# die cylinder, as in the patent. As the dial revolves, the points 4 catch one thread of the yarn, as shown in Figs. V and IX, and by holding this yarn back, a loop is formed by plication .referred to. o- `The points 4 being necessary `to devise some meansofdislodging the loops from the points,` as the dial re- 'volves finger 6, secured to' the franeof themachine, and theinner end of which is just beseries of projecting loops, as shown in my apvFig.A V, so thatas `the cylinderiturns, the

ing in contact with .the finger 6.v The.l manner in which the yarn is caught by the points and not being dislodged therefrom by the nger 6 until after the stitch is formed.

For plain work, in one direction, it is not necessary for the finger 6 to be moved, but if it is desired tonarrowthe Work, by turnthen it is necessary to provide vtwo of the iingers 6, as shown in Fig. I, and it isalso necessary to provide for the outward movement ofthe iinger, which is inactive for the time beingyinA order that. this tingerwill not interfere with the operation of the machine, so

work which has to be narrowed,'I mount the `fingers 6 on shafts or rods 7, secured by plates 13, carried- .by the fingers 6 impinge.' f The plates -13 and iingers 6 are connected by a hub loosely on the shafts 7. y

14 represents the yarn or thread guide, car-` riedby the spindle or shaft 3, and which is swung from side to side during the narrowing process, and as this guide comes against the outturned end l5 of the plate 13, it moves the plate and finger outv of the path of the points 4. The plate and linger are shown stationary, it' becomes j This is accomplished by aninclined I Y Y loops are dislodged from the point's4, by corn'4 ing themachine inthe opposite direction` that when it is desired to use the machine on- 14, so as tormove together, the hub fittingr f Yeach point, thus producing a fabric-having a I neath the path of thepoints 4, as shownin 4, between vthe needles l, is illustrated in Fig.v IX, the yarnv being drawnA over the points,

downturned ends against which the plates IOO movedto their outer position on the right side of Fig. .1. When the guide 14 isxthrown over tto `Fits other position, the plate and iinger, which are now shown as held out by the guide, move to their inner position against the stop 11, and as the guide reaches the other sideof its throw, it Amoves the other plate 13, and finger 6 out of Working position.

The construction and operation of the guide 14, per se, as Well as the construction and operation of the stationary guide 17, are well understood in knitting machines, and need no explanation. They have nothing to do with my present invention, except so far as the movable guide 14 acts to throw the finger 6 out of Working position, and as I have already stated, the finger 6 may be fixed and that isto knit without forming loops.

stationary, if `only plain Work is to be done on the machine, and of course only one Wi-ll f` mechanism Ijhave shown for accomplishingg this result is to form heads 2O on the inner ends ofthe poi.nts,iand surround these headsi shown in Fig. I.

Aby a spring `21, the forinof the spring being:`

22 .represents `a collartitting overfa 'ring23 on the shaft 3. This collar bearslat its lowerl end against the heads 2O of the points, andV is held 'to its adjustment by a set screw 24` fitting in a bayonet slot 25 in the collai-.f

When the collar is in lits lower position, thel points 4 are forced to their outer or Working?y position, and are held in this `ipositionby the collar.

They do not moveout andlin during the `operation ofthe machine, but are Lheld,

iixed inieither position.

-do plain work, the collar 25 is raised, :as

shown in 1N/,and the springl draws IE it is desired toi the points 4in `out of working position, ror; outfof a position Where they will catch the yarn to form a loop, and then the kmachine may be used as `an ordinary knitting machine without the loops being formed.

' 11n Fig. V I have shown the points4as sim-- The plates 13, it will be noticed,have a dat surface 13 on their inner faces. The object of this fiat surface is to receive those needles 1 which are elevated (when doing heel and `toe work) as they are passing the plates, the fiat surface being wide enough to extend froin `011e needle to another, so that the plates plates, the needles force the plates slightly y back away from the stops 1l, and as soon as the high needles pass the plates are forced back again `against the stops `by the springs.

By the use of a "finger for removing the loops from the points, I am enabled to make the loops veryclose together, and can, when desired, make a loop for each stitch, there being of course a point 4 for each needle 1.
